The eyeglass frame shape measuring unit 30 has a frame holding mechanismthat holds an eyeglass frame, and a measuring mechanism which measuresthe three-dimensional shape of a rim by detecting the movement of atracing stylus inserted into the groove of the rim of the eyeglassframe. The eyeglass frame shape measuring unit 30 may use a unit thathas a well-known configuration.

The display unit 40 has a display with a touch panel function. As theoperator touches a switch displayed on the screen of the display unit40, a signal corresponding to a display of the switch is input. Inaddition, the display unit 40 is used in common in a stage of measuringthe shape of a rim by the eyeglass frame shape measuring unit 30, astage of attaching a cup by the blocker unit 500, and a stage ofprocessing a lens LE by the lens processing mechanism section 10.

FIG. 2 is a schematic configuration diagram of the lens processingmechanism section 10 disposed in the housing 2. The processing apparatusbody 1 includes a lens holding section 100 having lens chuck shafts tohold a lens LE to be processed, and a processing tool rotating unit 160that rotates a processing tool rotating shaft 161 a to which a lensprocessing tool 168 for processing the peripheral edge of the lens isattached.

The processing tool rotating unit 160 is disposed in the front of thebase 170. The lens processing tool 168 is constituted by a roughinggrindstone, a bevel-processing and plano-processing finishinggrindstone, a flat-polish-finishing grindstone, and the like. Theprocessing tool rotating shaft 161 a is rotated by a motor 161.

The lens holding section 100 includes: a lens rotating unit 100 a thatrotates a pair of lens chuck shafts 102L and 102R; an X-direction movingunit (chuck shaft moving unit) 100 b that moves the lens chuck shafts102L and 102R disposed in a carriage 101 in an axial direction (Xdirection); and a Y-direction moving unit (inter-shaft distance changingunit) 100 c that moves the lens chuck shafts 102L and 102R in such adirection (Y direction) to approach or to be distant from the processingtool rotating shaft 161 a.

The lens rotating unit 100 a has a motor 120 that rotates the pair oflens chuck shafts 102L and 102R held in the carriage 101. In addition, amotor 110 for moving the lens chuck shaft 102R toward the lens chuckshaft 102L to nip the lens LE between the lens chuck shafts 102L and102R is disposed in the carriage 101. The base portion of a cup CUattached to the front surface of the lens LE is attached to a cup holder(illustration thereof is omitted) disposed on the lens chuck shaft 102L.

The X-direction moving unit 100 b has a motor 145. The carriage 101 ismounted on an X-axis movement support base 140 that is able to movealong shafts 103 and 104 extending in the X direction. The carriage 101is linearly moved in the X direction along with the support base 140 bythe rotation of the motor 145.

The Y-direction moving unit 100 c has a motor 150 mounted on the supportbase 140. The rotation of the motor 150 is transmitted to a ball screw155 extending in the Y direction, and the carriage 101 is moved in the Ydirection by the rotation of the ball screw 155.

The lens LE held by the lens chuck shafts 102L and 102R is moved in theX direction by the X-direction moving unit 100 b such that the positionin the X direction thereof with respect to the lens processing tool 168is changed. In addition, the distance of the lens LE from the processingtool rotating shaft 161 a is changed by the Y-direction moving unit 100c so as to be subjected to peripheral edge processing based on a targetlens shape.

In the rear of the carriage 101, a lens shape measuring unit 200 isdisposed. The lens shape measuring unit 200 has a tracing stylus 260that comes into contact with the front surface and the rear surface of alens, and the shapes of the front surface and the rear surface of thelens are measured by detecting the movement position of the tracingstylus 260. During lens shape measurement, the lens LE is rotated andthe Y-direction moving unit 100 c is driven on the basis of a targetlens shape, and the position in the X direction of the refractivesurface of the lens with which the tracing stylus 260 comes into contactis detected by a sensor (not shown).

FIG. 3A is a schematic configuration diagram of the blocker unit 500.FIG. 3B is a diagram of a state where a cup attaching portion 560 inFIG. 3A is directed downward. FIG. 3C is a diagram of the blocker unit500 of FIG. 3B viewed in an arrow A01 direction. FIG. 4 is a diagram ofan optical system disposed in the blocker unit 500. The blocker unit 500includes lens support portions (support pins 505) disposed to supportthe lens LE on a reference axis L01 extending in the vertical direction,a support arm 562 to which the attaching portion 560 to which the baseportion of the cup CU is attached is attached, moving arms 556 that holdthe support arm 562 to be rotatable about an axis extending in thelateral direction as the center, and are movable in the upward anddownward direction which is the direction of the reference axis L01. Themoving arms 556 hold the support arm 562 to be rotatable about an axisX02 extending in the lateral direction so that the attaching portion 560is directed in a first direction which is a downward direction, aforward direction in which the operator is positioned with respect tothe blocker unit 500, or a second direction which is an upwarddirection.

In addition, the blocker unit 500 has a lever 564 operated by theoperator to rotate the support arm 562 so that the attaching portion 560is directed in the first direction from the second direction. The leveris disposed in the support arm, and preferably, is also used as anoperation member for lowering the cup CU attached to the attachingportion 564 along with the moving arms 556 by the operator after theattaching portion 564 is directed in the first direction.

In addition, it is preferable that the blocker unit have a firstimpelling member (spring 555) that impels the moving arms 556 in theupward direction, a second impelling member (spring 559) that applies animpelling force to rotate the support arm so that the attaching portionis directed in the second direction from the first direction, and arestriction portion 570 that restricts rotation of the support arm sothat the center of the attaching portion is positioned on the referenceaxis L01 when the support arm is rotated to cause the attaching portionto be directed in the first direction.

In addition, the impelling force of the first impelling member is set tobe greater than the impelling force of the second impelling member.Moreover, it is preferable that the impelling force of the firstimpelling member be greater than a moment load in the lever when thesupport arm is rotated by the impelling force of the second impellingmember. In addition, it is preferable that the second direction in whichthe attaching portion is directed be in a range of a direction rotatedtoward the operator side by 45 degrees to 180 degrees with respect tothe downward direction of the reference axis L01.

A specific example of a cup attaching mechanism of the blocker unit 500is as follows. In FIGS. 3A and 3B, a transparent plate 503 is disposedon a pedestal 502. On the transparent plate 503, three support pins(lens support portions) 505 are provided about a reference axis L01 forcup attaching as the center. The lens LE is placed on the support pins505. Two support columns 552 are attached to extend upward from thepedestal 502. The upper ends of the support columns 552 are supported bya block 566. Movement support bases 554 to which the moving arms 556 areintegrally attached are attached to the support columns 552 to bemovable in the upward and downward direction. The spring 555 as theimpelling member that always impels the movement support base 554 in theupward direction is disposed in the movement support base 554. Two arms556 are disposed to extend forward from the movement support base 554. Ashaft 558 which is a coaxial with the axis X02 that extends in thelateral direction is mounted to the front portion of the arm 556.

The support arm 562 that supports the cup attaching portion 560 is heldby the arm 556 to rotate about the shaft 558 (the axis X02) so that thecup attaching portion 560 is directed forward (forward an operator) andthe cup attaching portion 560 is directed downward. The base portion ofthe cup CU which is a tool for holding the lens LE with the lens chuckshafts 102L and 102R of the lens LE is mounted to a hole provided in thecup attaching portion 560. In addition, a lever 564 for enabling theoperator to rotate the support arm 562 is fixed to the support arm 562.The lever 564 has a plate shape.

The coil spring 559 as the impelling member is disposed in the shaft558. When the operator does not operate the lever 564, the coil spring559 applies an impelling force to rotate the support arm 562 so that theattaching portion 560 is directed in the second direction (forwarddirection) from the downward direction. In addition, the impelling forceof the spring 555 is set to be greater than the impelling force of thecoil spring 559.

When the lever 564 is operated by a finger of the operator and thesupport arm 562 is rotated so that the center of the cup attachingportion 560 is positioned on the reference axis L01 as illustrated inFIGS. 3B and 3C, the restriction portion 570 for restricting therotation of the support arm 562 is provided in the moving arms 556. InFIG. 3C, as a cut-off part 563A formed in the support arm 562 abuts onthe restriction portion 570, the rotation of the support arm 562 isrestricted in a state where the cup attaching portion 560 is directed inthe downward direction.

In addition, separately from the cut-off part 563A, a cut-off part 563Bis formed in the support arm 562. When the cup attaching portion 560 isrotated to be directed in the forward direction by the coil spring 559,the cut-off part 563B abuts on the restriction portion 570 such that therotation of the support arm 562 is restricted. The restriction portion570 is also used as a restriction portion that restricts rotation of thesupport arm 562 to cause the cup attaching portion 560 to be directed inthe second direction.

In addition, the lever 564 extends substantially in the upward directionas illustrated in FIG. 3A when the attaching portion 560 is directed inthe forward direction (second direction), and the lever 564 is disposedto extend substantially in the horizontal direction (in a range of ±30degrees with respect to a surface orthogonal to the reference axis L01)when the attaching portion 560 is directed in the downward direction(first direction). Therefore, the operator continuously performs anoperation of the lever 564 when the attaching portion 560 is directed inthe downward direction from the forward direction and an operation ofthe lever 564 when the attaching portion 560 is lowered toward the lensLE placed on the support pins 505 in association with each other.

In addition, the second direction in which the attaching portion 560 isdirected is a direction in which the operator substantially faces thefront in the example of FIG. 3A. However, the second direction in whichthe attaching portion 560 is directed may be a range of a directionrotated by 45 degrees to 180 degrees with respect to the downwarddirection of the reference axis L01. In this range, the base portion ofthe cup CU may be attached to the attaching portion 560 while theoperator views the hole of the attaching portion 560.

A cup attaching operation by the cup attaching mechanism as describedabove will be described. When the operator does not operate the lever,as illustrated in FIG. 3A, the attaching portion 560 is in a state ofbeing directed in the forward direction (second direction) by the coilspring 559. The operator mounts the base portion of the cup CP to theattaching portion 560 in this state. Here, the operator is able to checkthe hole of the attaching portion 560, and thus it is easy to mount thebase portion of the cup CU to the attaching portion 560.

The operator operates the lever 564 and rotates the lever 564 directedin the upward direction toward the forward direction. Here, an impellingforce is applied by the coil spring 559 in the direction in which theoperator rotates the lever 564. When the operator rotates the lever 564against the impelling force, the rotation of the support arm 562 (theattaching portion 560) is restricted by the restriction portion 570.Here, a state in which the attaching portion 560 is directed in thedownward direction is achieved, and the lever 564 is substantially inthe horizontal direction, and a force of the operator for operating thelever 564 is in the downward direction. In addition, an impelling forcein the upward direction is applied to the moving arms 556 to which thesupport arm 562 is attached by the spring 555. However, since theimpelling force of the spring 555 is set to be greater than theimpelling force of the coil spring 559, the moving arms 556 are notlowered until the rotation of the support arm 562 is restricted by therestriction portion 570. After the rotation of the support arm 562 isrestricted by the restriction portion 570, when the operatorcontinuously presses the lever 564, the pressing force is directed inthe downward direction, and thus the attaching portion 560 and the cupCU are lowered along with the moving arms 556. Accordingly, the cup CUis fixed to the front surface of the lens LE.

After fixing of the cup CU to the lens LE is completed, when theoperator raises the finger in the upward direction and removes thefinger from the lever 564, the support arm 562 is raised along with themoving arms 556 by the spring 555, and the rotation of the support arm562 is returned to its original state by the coil spring 559.Accordingly, the position and the direction of the attaching portion 560are returned to the initial states.

In the apparatus of JP-A-2008-246634, the operator need to perform afirst operation of rotating an arm having a attaching portion into whicha cup is inserted in the horizontal direction about an axis in theupward and downward direction as the center, and a second operation oflowering the arm. However, the direction of the first operation and thedirection of the second operation are different, have no association inthe operation directions, and have no continuity. Contrary to this, inthe blocker unit 500 described in the specification, after performingthe operation of bringing down the lever 564 directed in the upwarddirection to be lowered, the operator performs the operation ofcontinuously pressing the lever 564 in the downward direction, therebyfixing the cup to the lens.

FIG. 4 is a diagram of the optical system disposed in the blocker unit500. The blocker unit 500 includes an illumination optical system 520that illuminates the lens LE, and an imaging optical system 530 thattakes an image of the lens LE. The illumination optical system 520includes: a light source 521 such as an LED that emits white light; amirror 523 that changes the direction of the illumination light; and aretroreflective member 527 disposed at the lower side of the transparentplate 503. The retroreflective member 527 is a member that has acharacteristic of reflecting incident light in its original incidentdirection. The lens LE placed on the support pins 505 is illuminatedfrom the below by the retroreflective member 527.

The imaging optical system 530 uses the mirror 523 of the illuminationoptical system 520 in common, and a half mirror 531 is disposed betweenthe mirror 523 and the light source 521. In the reflected direction ofthe half mirror 531, an aperture 532, a lens 533, and an imaging element(camera) 534 are disposed. The aperture 532 is disposed at a positionthat is substantially a conjugate of the light source 521 via the halfmirror 531. The optical axis of the imaging optical system 530 (the lens533) is disposed to be aligned with the reference shaft L01. Inaddition, the focal position of the imaging optical system 530 is set tosubstantially focus on the surface of the lens LE placed on the supportpins 505. The image of the front surface side of the lens LE is imagedby the imaging element 534 of the imaging optical system 530. The imageof the lens LE taken by the imaging element 534 is displayed on thedisplay unit 40.

FIG. 5 is a control block diagram associated with the eyeglass lensprocessing apparatus. A memory 51, the lens processing mechanism section10, the eyeglass frame shape measuring unit 30, the display unit 40, andthe blocker unit 500 are connected to a control section 50. The controlsection 50 receives an input signal through the touch panel functionincluded in the display unit 40 and controls a display of figures andinformation on the screen.

In addition, the display unit 40 is used in common in the stage ofmeasuring the shape of a rim by the eyeglass frame shape measuring unit30, the stage of attaching the cup by the blocker unit 500, and thestage of processing the lens LE by the lens processing mechanism section10. In addition, through the display unit 40 as the center, the operatorhas the display unit 40 as the center in the arrangement of the window12, the eyeglass frame shape measuring unit 30, and the blocker unit 500as described above, and thus the movement of the line of sight of aworker and the distance of the flow line of a work are shortened.Therefore, the operator may efficiency perform the work in each stage.

Next, the operations of the apparatus will be described. FIGS. 6 to 12are examples of screens switched and displayed on the display unit 40.In each of the diagrams, a switch 404 a is a switch that inputs a signalfor switching to a screen of the next operation order. The controlsection 50 sequentially switches predetermined screens according to eachof the operations processes including rim shape measurement, cupattaching, and lens processing on the basis of the input signal forscreen switching by the switch 404 a and displays the screens on thedisplay unit 40.

As the initial work process, first, the operator performs measurement ofthe shape of the rim of an eyeglass frame using the eyeglass frame shapemeasuring unit 30. When a trace mode is selected from a menu screen(illustration thereof is omitted) displayed on the display unit 40, asillustrated in FIG. 6, a screen 410 for starting the measurement by theeyeglass frame shape measuring unit 30 is displayed on the display unit40. On the screen 410, a switch 411 a for starting measurement of theright rim of the eyeglass frame, a switch 411 b for starting measurementof the left rim, and a switch 411 c for sequentially starting themeasurements of the right rim and the left rim are displayed.

In FIG. 6, the switch 404 a is a switch that inputs a signal forswitching to a screen of the next process. A switch 404 b is a switchthat inputs a signal for returning to the previous screen. In addition,a switch 402 a is a switch that sends a command to nip the lens LE withthe pair of lens chuck shafts 102L and 102R included in the lensprocessing mechanism section 10. A switch 402 d is a switch that inputsa signal for stopping lens processing on the way. The switches 402 a and402 d may not be displayed on the screens in stages in which processingof the lens LE is not performed.

When the switch 411 c of FIG. 6 is selected and measurements of theright rim and the left rim are performed by the eyeglass frame shapemeasuring unit 30, the measurement result (target lens shape) is stored(input) in the memory 51. After measurements of the shapes of the rims,when the switch 404 a is pushed, the screen of the display 40 isswitched to a screen 415 illustrated in FIG. 7. In the screen 415,target lens shape figures TS are displayed as the target lens shapes ofthe left rim and the right rim. In addition, a value indicating a framepapillary distance FPD between the left and right rims is displayedthrough the measurements of the left and right rims. As the screen 415is displayed, the operator is able to see that the left and right targetlens shapes are obtained by the eyeglass frame shape measuring unit 30and is able to confirm the shapes of the target lens shapes.

Next, when the switch 404 a is pushed, the screen of the display 40 isswitched to a screen 420 for inputting processing conditions for thelens LE as illustrated in FIG. 8. By displaying the screen 420, theoperator may recognize that inputting of processing conditions is neededin this stage. On the screen 420, the material of the eyeglass frame maybe selected by a switch of a display portion 422 s, the material of thelens LE may be selected by a switch of a display portion 422 n, and thekind of the lens LE (single vision lens, bifocal lens, progressive lens,and the like) may be selected by a switch of a display portion 422 c. Inaddition, processing modes (bevel-processing, plano-processing, and thelike) and chamfering may be selected by switches of a display portion424. In addition, in the display portion 424, a switch that selects thecenter of attaching of the cup with respect to the lens LE from theoptical center of the lens and the center of the target lens shape isdisposed.

When the switch 404 a on the screen 420 of FIG. 8 is pushed, asillustrated in FIG. 9, the screen of the display unit 40 is changed to ascreen 425 to which data for a layout of the positional relationship ofthe lens with respect to the target lens shape is input. For example,the screen is switched to the input screen 425 for a layout of theoptical center OC of the lens LE with respect to the geometric center FCof the target lens shape. By displaying the screen 425, the operator mayrecognize that inputting of layout data is needed in this stage. Bytouching display fields of numerical values of the screen 425, layoutdata including the papillary distance PD of a wearer, the height of theoptical center OC with respect to the geometric center FC, and the likemay be input. The input layout data is stored in the memory 51. Inaddition, the input screen 425 for the layout may be a screen that alsofunctions as the input screen 420 for the processing conditions of FIG.8.

When the switch 404 a on the screen 425 of FIG. 9 is pushed, in the nextstep, the screen of the display 40 is switched to a screen 430illustrating a transition to the cup attaching process by the blockerunit 500 as illustrated in FIG. 10. Accordingly, the operator mayrecognize that the cup attaching work is needed. In addition, the screen430 is a display example in a case where the lens LE for the right eyeis selected by a switch 402 b.

The cup attaching operation using the blocker unit 500 will be simplydescribed. The operator places an unprocessed lens LE on the supportpins 505 of the blocker unit 500. The lens LE is illuminated by theillumination optical system 520, and the image of the lens LE is takenby the imaging element 534. A lens image LEM taken by the imagingelement 534 is displayed on a display portion 432 of the screen 430. Thelens image LEM also includes an image 434 b of a printed dot mark thatis attached in advance. In the display portion 432, a target lens shapefigure TS for the right eye obtained by the eyeglass frame shapemeasuring unit 30 is displayed by being synthesized (superimposed) withthe lens image LEM. The display position of the target lens shape figureTS on the display portion 432 is determined on the basis of the layoutdata and selection of the position of the cup attaching center, and thedisplay of the target lens shape figure TS is controlled by the controlsection 50. In addition, the display portion 432 displays a guide mark435 for aligning the position of the printed dot mark image 434 b, whichis synthesized (superimposed) with the lens image LEM. As the operatormoves the lens LE to enable the guide mark 435 and the printed dot markimage 434 b have a predetermined positional relationship, the positionof the reference axis L01 may be aligned with the cup attaching centerof the lens LE. In addition, by observing the positional relationshipbetween the outside diameter of the lens image LEM and the target lensshape figure TS, whether or not a lens diameter from the target lensshape (peripheral edge processing shape) is insufficient may beconfirmed. In addition, a display portion 431 displays setting data forthe layout data and the processing conditions (detailed illustration isomitted).

After completing the alignment of the position of the lens LE, asdescribed above, the operator rotates the lever 564 in the downwarddirection and further lowers the lever 564. Accordingly, the cup CU isattached to the surface of the lens. The cup CU is attached to the lensLE for the left eye in the same order.

When the switch 404 a on the screen 430 is pushed, as illustrated inFIG. 11, a screen 435 illustrating a transition to a stage in which lensprocessing is able to be performed by the lens processing mechanism 10is displayed. For example, on the screen 435, a switch 402 c that inputsa signal for allowing the lens processing mechanism section 10 to startprocessing of the lens LE is displayed. In addition, the switch 402 bthat inputs a signal for selecting any of the left and the right of thelens LE to be processed is displayed. Accordingly, the operator mayrecognize that the stage proceeds to the stage of performing theprocessing of the lens LE as the next stage. In addition, at the centerof a screen 435, as in FIG. 9, a display for checking the layout data ismade.

The operator opens the window 12 disposed above the lens processingmechanism section 10 and holds the lens LE with the lens chuck shafts102L and 102R. When a signal of the switch 402 a is input, the motor 110is driven by the control of the control section 50 to move the lenschuck shaft 102R. Thereafter, when the switch 402 c is pushed, thecontrol section 50 executes lens shape measurement using the lens shapemeasuring unit 200.

After completing the lens shape measurement, when the switch 404 a ofthe screen 435 of FIG. 11 is pushed, the screen is switched to a screen440 of FIG. 12. The screen 440 is an example of a simulation screenduring bevel-processing. On the screen 440, the target lens shape figureTS, and a figure 442 of a bevel cross-section at the edge positiondesignated by a cursor 444 are displayed. The position of the cursor 444may be changed by switches 445 a and 445 b. The bevel position for thelens edge during bevel-processing may be adjusted by changing the valueof condition data of a display field 446. By displaying the screen 440,the operator may confirm whether or not it is appropriate to performbevel-processing, and conditions of bevel-processing may be changed. Inaddition, when the switch 402 c is pushed again, driving of theX-direction moving unit 100 b and the Y-direction moving unit 100 c iscontrolled, and processing of the peripheral edge of the lens LE isperformed by the lens processing tool 168.

As such, since screens in a predetermined order according to theoperation processes including rim shape measurement, cup attaching, andlens processing are sequentially switched and displayed on the basis ofthe input signals while the screens are switched, an operator who isunaccustomed to processing may also smoothly work. In addition, byfollowing the switched displays of the screens, inputting of data neededfor processing is accurately performed. Accordingly, the operatorefficiently performs a series of the works including rim shapemeasurement, cup attaching, and lens processing.
